navigator.cookieEnabled returns a Boolean value that indicates whether cookies are enabled or not. The property is read-only.

句法

var cookieEnabled = navigator.cookieEnabled;

cookieEnabled 是布尔 : true or false .

注意： When the browser is configured to block third-party cookies, and


							navigator.cookieEnabled

is invoked inside a third-party iframe, it returns


							true

in Safari, Edge Spartan and IE (while trying to set a cookie in such scenario would fail). It returns


							false

in Firefox and Chromium-based browsers. 注意： Web browsers may prevent writing certain cookies in certain scenarios. For example, Chrome 80+ does not allow creating cookies with


							
								SameSite=None

属性， unless they are created over HTTPS and with


								Secure

属性。

范例

if (!navigator.cookieEnabled) {
  // The browser does not support or is blocking cookies from being set.
}
